How to Create a Private Multiplayer Terraria Server with Hamachi

Part 1: Create a Private Network

1. Download and install Unmanaged LogMeIn Hamachi
2. In Hamachi, click Power On
3. Within Hamachi, click Network -> Create a New Network
   
4. Create a unique Network ID and Passsword
   

Part 2: Create a Terraria Server

1. Start up Terraria
2. Click Multiplayer -> Start Server -> Choose a World (or create a new one) -> Create a Password (or leave it blank) and click Accept
3. DO NOT CLOSE THIS INSTANCE OF Terraria

Part 3: Join your world

1. Open up ANOTHER instance of Terraria. You must have 2 instances of Terraria running if you want to host and play on your multiplayer server.
2. Click Multiplayer -> Join -> choose your character -> then enter your IP from Hamachi.
   5.247.115.30 would be my IP in this example
   

Part 4: Get your friends to join your server

1. Anybody that wants to join your server must also Download and install Unmanaged LogMeIn Hamachi
2. After Hamachi is installed, click Network -> Join an existing network..., then enter the Network ID and password you created in Part 2. The Network ID and password are both case sensitive
3. You should now see a list of everybody else who is connected to your group
4. Open up Terraria. Click Multiplayer -> Join -> Choose Character -> Enter Server IP Address
5. The server IP is the group of numbers next to the name of whoever is hosting the server.
   5.247.115.30 would be the IP to use in this example
